CNC machining of die casting molds requires the use of CNC machine tools, such as CNC milling machines, CNC lathes, and EDM machines. With these equipment, drilling, milling, turning, and electrical discharge machining (EDM) operations can be performed to manufacture mold components with precise shapes and dimensions.

Surface treatment of die casting molds often involves chrome plating, nickel plating, or coating methods. These treatments enhance the mold's wear resistance, corrosion resistance, and surface smoothness, while reducing adhesion and friction between the mold and molten metal, thereby extending the mold's lifespan.

In summary, CNC machining of die casting molds is the process of precisely machining high-strength tool steel materials using CNC machine tools to manufacture high-quality die casting molds. These molds are widely used in various die casting processes for producing metal parts and components.
